In CodeIgniter Project, Open config.php file in config folder. Set value for base_url config as below:

$config['base_url'] = 'http://localhost:9092/LearnCodeIgniterWithRealApps/';

Create new PHP file named demo.php in controllers folder as below:

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Demo extends CI_Controller {

	public function index()
	{
	    $data['age'] = 20;
	    $data['username'] = 'PMKLab';
	    $data['price'] = 4.5;
		$this->load->view('demo/index', $data);
	}
}

In CodeIgniter Project, Open routes.php file in config folder. Set value for default_controller as below:
